EDWARD HUBER, OF MARION, OHIO.

CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 257,709, dated May 9, 1882,

' Application filed March 10, 1882. (Model.)

To all whom tt may concern Beitknown that I, EDWARD HUBER, of Marion, in the county of Marion, and in the State of Ohio, have invented certain new and useful Improvements in Oar-Axles Boxes; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, makinga part of this specification.

This invention relates to improvements on car-axle boxes; and the nature of my invention consists in the combination of beveled lugs formed on a circular flange surrounding the feed-aperture of a car-axle box with a lid or cover having interlocking lugs formed on it, which lid or cover is hinged to a pintle of segment form, so that the lid can swing freely toward and from said feed-aperture, and also be moved bodily about its axis in the act of engaging and disengaging the said lugs, as will be hereinafter explained.

The invention also consists in the combination of a spiral spring on the said pintle-segment with the hinged lid or cover and the interlocking lugs, as will be hereinafter explained.

The following description of my invention, when taken in connection with the annexed drawings, will enable others skilled in the art to understand it.

In the annexed drawings, Figure 1 is a front elevation of acar-axle box having my improved lid or cover applied to it. Fig. 2. is a section taken longitudinallythrough Fig. 1. Fig. 3 is an end elevation of the axle-box, showing the lid or cover open. Fig. 4 is a detail showing a lug on the cover interlocked with a lug on the box-flange.

A designates a car-axle box, and B the brass or axle bearing therein. The outer end, 0, of this box is inclined, as shown in Fig. 2, and the feed-opening through this end 0 is circular, and surrounded by a protruding flange or collar, D, on the circumference of which two lugs, a a, are formed and arranged diametrically opposite each other. The ends of each lug a is beveled or made wedging for a purpose hereinafter explained.

On one side of the inclined end 0 of the box A extensions 1) b are formed, and on the faces of these extensions ears 0 c are rigidly applied,

an arm or wing, d, through which freely passes the segment-pintle E, thus forming the hinge of the cover, which will allow the latterto swing open and shut, to be moved bodily up or down, and to be moved circularly about its own axis. Opposite the arm or wing d is a loaded handle, e, formed on the edge of the cover, which is convenient for use in opening or shutting it, and which also serves, in connection with a helical spring,f, surrounding the pintle E, to aid in tightening the cover when it is shut against the flange or collar D.

On the inner face of the cover G, least two hooking orinterlocking lugs, gg, arranged dinmetrically opposite each other, and adapted to engage with the lugs to a on the collar D. The grooves in the lugs gg are tapered, so that they receive the outer ends of the lugs a a with a drawing action when the cover is slightly turned about its axis after the two sets of lugs are interlocked. The bcvels or wedges of the lugs a a, acting on the lugs g y, will tightly draw the cover against the end of the flange D and make a closejoint.

It will be seen from the above description that when the cover is shut and the lugs a a and g g are caused to register properly with each other the weight or handle a will cause the cover to turn about its axis and assume a locked position. The springfwill assist the loaded handle 0 to effect the locking of the cover, although I do not confine myself to the use of the spring. To open the box it is only necessary to slightly raise the handle 6 and swing the cover around on its hinge.

It is obvious that my invention is not con fined to the loaded handle nor to the spring. Either one or both will effect the rotary movement of the'cover about its axis.

Having described my invention, I claim- 1. The combination of the axle-box A, the interlocking lugs on the collar surrounding the IOG feed-opening therein, the cover hinged to a 'In testimony whereof I uffix my signature, IO

, segment-pintle, the interlocking lugs on the inpresenee of two witnesses, this 27th day of cover, and the loaded'handle, substantially as described.

2. The combination of the axle-box provided withlu gs, the hinged cover provided with interlockinglugs,thesegment-pintle, and the spring applied on this pintle, substantially as and for the purposes described.

February, 1882.
